Hey guys, new poster, but long time reader here. I have had the PD35 for around a year now, and have been very happy with it. I just ordered a UC35 from Amazon last week, and it arrived the other day.
I've noticed that when pressing the tail cap button in halfway (but firmly) in momentary mode, there is a quick flash of light, and then the light comes on as normal. This only happens in the two (or sometimes, but rarely, three) lowest modes, and the flash is always the same intensity as the mode the light it in. I've googled and read about preflash problems, but they seem to be talking about having the light in low mode, and it flashing in the highest mode on startup. My light flashes, but the intensity of the flash is the same as the mode.
I've tried to recreate this on my PD35 with no luck.
Additionally, I've noticed that it doesn't happen every time. It may happen about half of the time. It seems less likely to happen if the light has been on in the last few seconds. Fro example, If I press the momentary button 4 times with about 1 second in between presses, it will preflash on the first press, but not the others. Then if I wait about 5 seconds and repeat, it will do it again only on the first press.
I am wondering if this is a sign of a bad component (maybe a capacitor that has to 'charge' up on startup, but has some residual charge when the light was on recently?) in the regulating circuit that I need to worry about failing soon.
Can anybody with this light try (in eco mode is fine) and let me know if they see similar behavior?
For a $100 light, I am thinking it shouldn't do that and am thinking about trying to get it replaced before it fails all together?
Thanks!
